At present, typical deodorants use as much as 80% ethanol or propylene glycol, or both. Its components have many shortcomings. Ethanol has a drying effect on the skin, but it can cause different degrees of irritation. Propylene glycol can also produce skin. Irritation or allergies, especially when the concentration in the formula exceeds 10%, and liquid silicone is basically non-toxic, and it will not cause irritation to injured and abraded skin. Therefore, the deodorant made of silicone oil and cyclic siloxane can overcome the above-mentioned characteristics, and at the same time improve the lubricity of the preparation, make the deodorant extraordinarily soft, and control the production of apocrine components in the human body. Achieved the purpose of deodorization. Polydimethylsiloxane polyol copolymer can improve the compatibility of many commonly used deodorant raw materials with other ingredients.
